What 3 factors affect resistance?
Resistivity, length, and cross sectional area
Cooperative binding of Oxygen
Each successive oxygen bound to hemoglobin increases the affinity of other subunits, while each successive oxygen released decreases the affinity of other subunits
Hydrostatic pressure
Force per unit area that the blood exerts against the vessel walls. Hydrostatic pressure pushes fluid out of the bloodstream and into the interstitium through the capillary walls.
Osmotic pressure
Also called oncotic pressure. A “sucking” pressure generated by solutes as they attempt to draw water into the bloodstream
Due to kidney disease, a person is losing albumin into the urine. What effect is this likely to have within the capillaries?
Decreased oncotic pressure
